To all whom it may concern Be it known that I, WILLIAM ran, a citizen of the United States, residing; at Medicine Lake, in the county of Valley; and State of Montana, have invented cer; tain new and useful Improvements ini Straw-Decks for Separators, of which the following is a specification, reference being had to the accompanying drawmgs.

This invention relates to improvements in straw decks for grain separators and has in common use without necessitating any material alterations in their construction.

With the above and other objects in view as will become apparent as the description proceeds, the invention consists in certain constructions, combinations and arrangements of the parts that I shall hereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawing,in which Figure 1 is a top plan View of a straw deck or rack embodying the present invention; Fig. 2 is a bottom plan view thereof. Fig. 3 is a longitudinal section of one of the rack sections, and Fig. 4 is a transverse section thereof taken onthe line 41-4 of Fig. 8. Referring in detail to the drawing, 5 designates a series of deck or rack sections. I have illustrated in the drawings, six of these separating sections, though itwill be understood that a greater or less number of.

the same may be employed if desired. As these deck sections are all of the same construction, the detail description of one of them will suffice for all.

In constructing the deck or rack section, I employ the two side walls indicated at 6 which are arranged in parallel relation. These side walls maybe of any desired length in accordance with the size and capacity of the thresher and are provided upon their upper edges with coarse teeth 7. The lower edges of these side walls have relatively fine teeth 8 provided thereon and to the inclined edges of these teeth, the

straw decks.

It will thus be seen that these plates are spaced from each otheri and constitute a riddle-through which the grain which has been separated from the straw falls upon a f transverse plates9 are hired at, their ends.

. The-upper edges of the side walls 6 are downwardly-inclined or. curvcd' at. their forward ends as indicated at 10 and at their rear ends, these walls are upwardly curved as shown at 11 to elevate the straw at its discharge point. j I

The deck or rack sections 5 are oscillated through the medium of the crank shafts 12 which extend transversely beneath the deck sections. The cranks of these shafts alternately extend in opposite directions and are mounted in suitable journal boxes 13 secured to the under side of each of the Two of these crank shafts are employed, the same being located adjacent the opposite ends of the rack. To the end of one of said shafts, a belt wheel or pulley 14 is secured for engagement by a suitable driving belt 15 extending from a suitable source of ower. The opposite ends of the crank shafts are each provided with the wheels or disks 16 to which the opposite ends of the pitmen 17 areeccentrically con nected. It will thus be apparent, that when the crank shafts are rotated, the alternate rack or deck sections are moved in relatively opposite directions vertically and longitudinally. Thus the straw is moved longitudinallv upon the toothed upper edges of the side walls of the deck sections and thoroughly agitated and broken to dislodge the grain therefrom. This grain falls down wardly upon the obliquely inclined spaced plates 9 constituting the bottom of each deck section and through the spaces between said plates.

From the foregoing, the construction and manner of operation of my improved straw rack or deck will be fully understood.

The device is comparatively simple in its construction, and by providing the coinparatively high side walls, the straw is carried longitudinally over the rack in spaced relation to the riddle plates, so that a more effectual separation of the grain from the straw will be obtained.

The device as a whole is simple and du a is believed that rable in its construction and may pro- I v duced at small manufacturing cost.

any of the advantages thereof.

While I have shown anddescribed the preferred form and construction of the several elements employed,"it will "be ob-' vious that'the invention is susceptible of considerable -modification without de arting'from the essential'featuresor sacrilihing 1 lower edges of said walls having inclined edges facing forwardly, said side Walls having the upper edges curved downwardly at their forward ends and the lower edges curved upwardly at the rearward ends thereof, riddle plates secured at their ends to the inclined edges of the teeth on the lower edges of the side walls for arrangement in spaced relatlon to one another, and means in connection with said sections to alternately reciprocate the same in opposite directions.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
